ABSTRACT:
A cup (2) of the centrifuge has two chambers (1,3). In the first chamber is placed the first blood bag (6) filled with blood fluid, which is inserted into the chamber together with an elastically deformable inset cup (4). A pressure pad (9) bears at one end on the outside (7) of the inset cup (4) and at the other end on the inside (8) of the chamber (1) of the centrifuge. During the centrifuging, the pressure pad (9) is admitted with pressure which results in a great volume increase. The inset cup (4) is thus compressed elastically so that the blood bag (6) is compressed and the blood components centrifuged in the blood bag are transferred corresponding to the volume increase of the pressure pad (9) into an empty satellite-blood bag arranged in the adjacent chamber (2). Over the upper connecting part (81) of the blood bag projecting from the chamber (1) is pushed a holder (64) which prevents bending of the connecting tube during the centrifuging process.
